Featuring a state of the art angular woven design, the vertical and horizontal lines are constructed together in such a way that it achieves 92000 micro holes per square feet. The difference of sound attenuation between 8kHz&12.5kHz and 500Hz is less than 1dB and 1.5dB resulting in outstanding sound transparency. The unique woven structure is designed to be 4K compatible and the fabric is compliant with all ROHS and REACH standards. Furthermore, the screen is also anti-UV, washable, mildew resistant, fire retardant and works in environments from -20 to 60c.
